Abstract The buried interface between the perovskite and electron transport layer (ETL) plays a vital role for further improvement of power conversion efficiency (PCE) stability solar cells (PSCs). However, it is challenging to efficiently optimize this as in bottom film. Herein, strengthening strategy constructing efficient stable PSCs by using CsI‐SnO 2 complex an ETL reported. CsI modification facilitates growth film effectively passivates interfacial defects. Meanwhile, gradient...
Black-phase formamidinium lead iodide (FAPbI3 ) with narrow bandgap and high thermal stability has emerged as the most promising candidate for highly efficient stable perovskite photovoltaics. In order to overcome intrinsic difficulty of black-phase crystallization eliminate (PbI2 residue, sequential deposition methods FAPbI3 -based will introduce external ions like methylammonium (MA+ ), cesium (Cs+ bromide (Br- structure.

The efficiency and stability of typical three-dimensional (3D) MAPbI3 perovskite-based solar cells are highly restricted, due to the weak interaction between methylammonium (MA+) [PbI6]4-octahedra in 3D structure, which can cause ion migration related defects. Here, we found that situ-grown perovskitoid TEAPbI3 layer on inhibit MA+ a polar solvent, thus enhancing thermal moisture perovskite films. crystal structure orientation reported for first time by single synchrotron radiation analysis....
Abstract The photovoltaic performance and long‐term stability of perovskite solar cells (PSCs) are greatly affected by trap states. Herein, a functional ionic liquid 1‐ethyl‐3‐methylimidazolium trifluoroacetate (EMIMTFA) is introduced, in which the cations (EMIM + ) can interact with PbI 2 to form stable one‐dimensional (1D) EMIMPbI 3 , trifluoroacetic acid anions (TFA − passivate interface between electron transfer layer layer. Unlike, widely studied low dimensional capping layers or...
Abstract Bulk lead halide perovskite films with unique optoelectronic properties and facile low‐cost processing methods are promising for various applications including photovoltaics. Solution‐processed colloidal inorganic nanocrystals higher crystallinity hold good potential devices better stability properties. To address phase defect passivation issues in black FAPbI 3 perovskite, all‐inorganic CsPbBr (CPB NCs) adapted as an effective modifier to form CPB NC‐treated (noted NC‐FAPbI ). It...
Abstract Microelectrode arrays, particularly Utah offer irreplaceable advantages in clinical applications and play a crucial role advancing brain‐computer interactions.

The phase stability and mechanical properties of binary W1−xTax W1−xRex alloys were investigated using the full-potential augmented plane-wave method. special quasirandom structures(SQSs) these are mechanically stable due to all positive elastic constants negative binding energies. energies both also exhibit energy favorable asymmetry toward W-rich side. In addition, bulk modulus decrease gradually with increase Ta concentration, while those Re concentration. Consequently, W metal can be...
Back projection algorithm (BPA) and range migration (RMA) are two common approaches for image reconstruction in synthetic aperture radar (SAR) imaging. Imaging is implemented spatial domain frequency domain, respectively these methods often considered to generate the same results. This true normal microwave/millimeter wave SAR imaging systems, since object of interests located far away applied wavelength long. In this case, location most important issue there no impetus with very fine...
Lead halide perovskite solar cells (PSCs) have achieved great progress and become one of the most promising candidates for next-generation low-cost high-efficiency photovoltaics (PVs). There are still many challenges toward successful commercialization, while use toxic lead a potentially large amount other related raw materials is main large-scale applications. Recycling chemical components in PSCs way resource saving recovery; however, currently, there few reports on recycling valuable...
Nowadays, terahertz (THz) imaging is quite promising in scientific and biomedical applications. However, the much longer wavelength degrades resolution of obtained images compared with classical at optical frequencies. Imaging considered to be a convolution process between object function point spread (PSF) system. Thus, how describe accurately from blurred image an inverse problem. In this paper, we demonstrate well such method can function. We would illustrate make current facilities...

5-Ammonium valeric acid iodide (AVAI) has been widely known as a stabilizer to enhance the stability of MAPbI3 perovskite, but its role and function is still under exploration. The typical 2D perovskites AVA2PbI4 have proposed capping layer for stabilization. Here, novel AVA-MA mixed-cation perovskite AVAMAPbI4 found show more even compact coverage than AVA2PbI4. A simple post-treatment on films by using AVAI isopropanol solution can fabricate such sample. This effectively passivates surface...
Hydrothermal liquefaction of the third-generation biomass represented by microalgae can produce biocrude. However, directly obtained biocrude has a high heteroatom content and low higher heating value (HHV), which cannot meet standards biofuel. In this work, water-insoluble was gained from hydrothermal (HTL) upgraded under four kinds solvents (i.e., methanol, ethanol, acetone, H2O) one type catalyst (H2O + Ru/C) at 240–400 °C for 1 h. The results show that HHV C H contents bio-oil increased...
